HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 841, 715 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 841, 715 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 841, 715 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 841, 715 is 1.
HCF(841, 715) = 1
HCF of 841, 715 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 841, 715 is 1.
Highest Common Factor of 841,715 is 1
Step 1: Since 841 > 715, we apply the division lemma to 841 and 715, to get
841 = 715 x 1 + 126
Step 2: Since the reminder 715 ≠ 0, we apply division lemma to 126 and 715, to get
715 = 126 x 5 + 85
Step 3: We consider the new divisor 126 and the new remainder 85, and apply the division lemma to get
126 = 85 x 1 + 41
We consider the new divisor 85 and the new remainder 41,and apply the division lemma to get
85 = 41 x 2 + 3
We consider the new divisor 41 and the new remainder 3,and apply the division lemma to get
41 = 3 x 13 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 841 and 715 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(41,3) = HCF(85,41) = HCF(126,85) = HCF(715,126) = HCF(841,715) .
